EKO EKOsynth P15 Vintage Analog Synthesizer. The top octave ic was the main issue here. Glad that there is a replica for this provided by http://www.flatkeys.co.uk. Faulty CA3080 were replaced by some LM13700 with adapter pcbs. Some logic ICs were faulty and replaced too. It Also needed a recap. And of course a good keyboard (contacs) cleaning. Couldn't do anythin to the front plate, but fixed the case.
